Thanks to every man and their dog having a GoPro (or similar device), we're likely going to continue seeing more of this sort of thing in the future, but that doesn't make it any less wild. Your heart would be between your ears if you saw a big, healthy looking bear chasing your friend who was only moments before, a second or two ahead of you on the trail. Is it real or fake? It sure looks legit. Would you stop or try and out run the bear?
